It looks like some of the earlier TBI units used a straight connector on their TPS sensor, and the later ones used a round one. Does anyone know if the sensors interchange (can I bolt a round plug one on one that came with a straight plug and vice versa)? ---------- Huh, thinking about it, same question about the air cleaner studs, can you use a single air cleaner stud on a TB that originally came with 2 studs?

No, you can't. I have a couple of spare TBI units just for parts and I just double-checked to make sure. The bolt holes are in different locations, and neither style TPS will fit on the other. Bolt lengths are different, too. You either have to get a different TBI unit or repin the harness. TurboCity makes an adapter harness, but it seems to me it would be cheaper just to make your own.

I am pretty sure you can. All the TBI units I have seen are pre-drilled and tapped for the single air cleaner studs. All you'd have to do there is just find that air cleaner stud, install it, remove the 2 original air cleaner studs, replace them with bolts like on the single stud TBIs, and that's it.

I'm pretty sure that you can just put the plug end that you need on your harness..The wires should be the same color to make it real simple

Yep, that's what I did, I got an old style connector from a junkyard and cut and spliced the connector in. Same colors, very easy.

Thanks guys...
